Boththe DMS100 & 5E support NI-1 & NI-2.
One feature that I recall with NI-2, mandatory 10 digit dialing on all outside calls.

FYI, for some reason, McLeod couldn't provide name & number CID off a DMS100 in central Iowa, but NI2 could. Don't know if that was a protocol, provider, or CO switch limitation.
I also found out about the 10 digit dialing the hard way. I was off site when they rebuilt the circuit. I logged in and made a test call, but my cell was long distance to the site, so I didn't find out about it until people started calling me with problems.. :-D

I join Dane in thanking everyone for the different responses. Differences (and mismatches) between ISDN protocol variants have caused headaches beyond belief for many. I forgot to mention the "4ESS" (custom) ISDN variant for the 4ESS tandem switches.
